Abstract

The electric power grids in the United States are slowly being converted into Smart Grids, which deploy digital technology that facilitates two-way communication between utilities and the customers, detect and react to local changes in usage. This conversion opens up many vulnerabilities and security pitfalls that never existed before.A recent example of an attack that had major impacts on the Power Grid is the cyber attack on the Ukrainian power grid. To combat these kinds of cyber attacks on critical infrastructures, we present a realistic moderate-cost modular test bed and evaluate using two case studies: Black Energy attack (2015) and Crash Override attack (2016) that happened in the Ukraine power grid. A design methodology for a modular test bed capable of performing a complex security assessment for cyber-physical systems is formulated, evaluated using the aforementioned attacks, some possible defense measures and some unique insights on these types of attacks are delineated. The experiments were carried out in PowerCyber test bed of Iowa State University
